Intergranular Fracture（沿晶断裂）
指材料断裂路径沿着晶粒边界扩展的失效模式。当晶界强度低于晶粒内部时，裂纹优先沿晶界网络传播，形成特征性的冰糖状断口形貌。该现象常见于以下场景：
晶界弱化机制
工程失效案例
核电设备不锈钢管道因晶界敏化导致的应力腐蚀开裂（可参考ASM Handbook失效分析案例），或高温镍基合金的硫致脆化断裂。
断口识别特征
扫描电镜下呈现明显晶粒轮廓，与穿晶断裂的韧窝/解理形貌形成对比，是失效分析的关键判别依据。
注：因未检索到可引用的公开权威文献链接，本文定义综合材料失效分析领域通用标准（如ASTM E3金相检验标准、ASM金属手册）中的术语规范。建议通过学术数据库（如ScienceDirect, SpringerLink）检索"intergranular fracture mechanism"获取具体实验研究文献。
Intergranular Fracture（沿晶断裂） 是材料断裂的一种形式，指裂纹沿着材料的晶粒边界（晶界）扩展，导致断裂面呈现沿晶粒界面分离的特征。以下是详细解释：
| 特征 | 沿晶断裂（Intergranular） | 穿晶断裂（Transgranular） |
|---|---|---|
| 裂纹路径 | 沿晶界扩展 | 穿过晶粒内部 |
| 断口形貌 | 颗粒状，晶界清晰 | 解理台阶、河流花样等 |
| 主导因素 | 晶界弱化（腐蚀、杂质） | 晶粒内部缺陷（位错、解理面） |
| 典型材料 | 不锈钢、铝合金 | 体心立方金属（如铁、钨） |
